The field of chemical solidification has just begun to mature into an accepted environmental technology for hazardous waste disposal. From the engineering point of view, some key issues still dominate the feasibility and effectiveness of hazardous waste solidification process. "Mixing" is essentially regarded as the most critical element but unfortunately, no evidence has been proposed to prove the homogeneity of the large monolith produced by solidification in order that the effectiveness of the solidification process can be evaluated in satisfactorily short time. The Homogeneity Evaluation by Video Imaging System (HEVIS) proposed in this study is to solve this problem with less time and economic feasibility.
The HEVIS for hazardous waste solidification process employs a fluorescent tracer in conjunction with video imaging analysis. This process provides an important basis for developing a new test method to evaluate the homogeneity of the final products of hazardous waste solidification. This study also shows the feasibility of HEVIS and proposes some recommendations for future applications.
